<pre wrap="">If this is the case, what DT are you using? Note that mainline kernel
armada-8040-mcbin.dts is meant for the DoubleShot, which has 88x3310 PHYs on
eth0 and eth1 (marked U2 and U3 on the PCB). These PHYs are not assembled on
the SingleShot. Instead, both interfaces are directly connected to SFP cages.
So the error message (-19 == -ENODEV) is correct. You need to remove the PHYs
description from the DT for the SingleShot.

<pre wrap="">I have Single Shot. And for vanilla I use armada-8040-mcbin.dts/dtb
Can you indicate me how change the dts? (maybe send me a patch), I see
multiple eth0, eth1, ... ref.

<pre wrap="">
The ethX reference is quite confusing indeed. When you see cpX_ethY it
refers to different Ethernet MAC instances on each CP. There are two
CP110 (cp0 and cp1), each with three Ethernet MACs.
For the Single Shot you can try the following completely untested patch
against v4.19.
